Kendall Square Station is a 234.7 MW natural gas fired combined cycle, petroleum liquids plant in Middlesex County. Kendall Station is a gas-fired combined heat and power plant in Cambridge, Massachusetts, run by Vicinity Energy. The original coal-fired station was built in 1948 by the Cambridge Electric Light Company, and a GE 7FA gas turbine was later tied in to form a combined cycle plant. NRG North America agreed in December 2013 to sell the 256-megawatt station to Veolia Energy North America and I Squared Capital, and Vicinity says it acquired the station with I-Squared the following year. It supplies steam to Boston and Cambridge customers, and a 42 MW electric boiler now makes carbon-free eSteam.
